I played ED initially with an Oculus DK2 starting back in 2014. Now using a Samsung Odyssey+. Between them, I have tried the following:
DK2 - My first VR set and now it seems ancient. But during it's day, it was great. Despite the SDE, I used this headset all the way into 2017! It had a big sweet spot, no god-rays, nice contrast and the VR immersion kept me playing Elite when I probably would have stopped if not for VR.
Oculus CV1 - Everyone knows about it and probably at one point tried it. In my opinion, not that much of a bump from the DK2 in regards of resolution. Yeah, slightly lower SDE but the god-rays...jeez. But a solid workhorse at its prime. Best touch controllers for games that use it.
HP WMR - Got it for $199 and wanted to see how the WMRs compared and worked. Honestly, I like the WMR sets. They are under-rated for what they can do. The Lenovo is probably the best of the original WMRs but I liked the HP due to the comfort and detachable cable since I used it with my gaming laptop and it was very portable. I found the HP WMR the most comfortable HMD and could wear it for hours without issues and no messed up hair..lol. The main drawback of the HP specifically was the tiny sweet spot. If you move your eye, the edges are blurry.
Oculus Go - Yes, I was curious how the screen looked in Elite since the new Rift S is technically using the same screen. I used ALVR and got it to work with Elite. The resolution and SDE were not bad and actually better than I expected. But I could tell a huge difference with not having an AMOLED screen as the colors and contrast were no match to the CV1 and Samsung O+. I'm afraid that if the Rift S display is indeed the exact same as the Go, it is a step-backwards in my opinion (no AMOLED or manual IPD either).
Samsung Odyssey+ - Probably the best deal (when on sale for $299) with great tech as it has the same resolution as the Vive Pro, manual IPD adjustments, beautiful AMOLED and an anti-SDE screen. No base stations to worry about and built-in bluetooth for the controllers. The main cons are a small vertical sweet spot (takes a while to 'lock' it in) and the comfort. This thing was extremely uncomfortable and I had a raging headache by an hour. BUT, if you replace the cover with a 3rd party like VR Cover and add a top strap (both about $30 each), it became very comfortable and is now my go-to and favorite HMD of all current sets I have tried. I play everything from Elite to Skyrim with it and love it. The anti-SDE does make a huge difference and I don't have issues with "soft" or "blurry" images as others may have indicated.
